air enters a horizontal, constant-diameter heating duct operating at steady state at 300 k, 1 bar, with a volumetric flow rate of 0.25 m3/s, and exits at 325 k, 0.95 bar. the flow area is 0.04 m2. assuming the ideal gas model with k 5 1.4 for the air, determine (a) the mass flow rate, in kg/s, (b) the velocity at the inlet and exit, each in m/s, and (c) the rate of heat transfer, in kw.
